M56 (May 2018)


M56 is a globular cluster visible in the constellation Lyra.  It is 32,900 light years or so away from us.  It appears to be traveling opposite the direction of most things in the galaxy, orbiting roughly backwards around the center.  Probably it was ripped off a small galaxy that was swallowed billions of years ago by the Milky Way.

This is just a monochrome image.  I enjoy imaging globs so that I can compare them with each other, so I have several of these taken with the same telescope and camera setup.  Then I can see their relative sizes and how many stars I can make visible.  For instance, compare M56 with NGC 7006 and M13.

This image is 10x720" with the SXVF-H9 through the CFF 290 Classical Cassegrain and an Astronomik CLS filter.
